Abstract (en)
The disclosure relates to a packaging material (1) with an integrated opening arrangement (4), and a method of producing the same. The foundation layer (3) of a packaging material web (1) or a packaging material sheet is provided with a hole (5) or a hole indication (15). The hole (5) or the hole indication (15) is covered by a thin thermoplastic strip (7). Thereafter, the packaging material (1) is finished, with other laminate layers (8, 9, 10, 12). In such instance, the outer layer (12) will wholly cover the strip (7). When the strip (7) is torn off, the hole (5) is exposed in that those layers (8, 9, 10, 12) which are sealed to the strip (7) accompany the strip (7) when torn off. <IMAGE>
